CoRN-PLANTER CHECK-Rowan.

SPECIFICATION forming part of VLetters Patent No. 239,596, dated April 5, 1881,

Application filed November 1; 1880. (Model.)

To all whom it may concern Be it known that I, LORENZO D. BENNER, a citizen of the United States, residing at Galesburg, in the county of Knox a-nd State of Illinois, have invented certain new and useful Improvements in Corn-Planter Check- Rowers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, `and to letters or figures of reference marked thereon, which form a part of this specification, in which- Figure 1 is a top plan of a construction embodying my invention. Fig. 2 is saine View as Fig. 1, but the parts shown in different rela-A tive positions. Fig. 3 is a perspective of one of the rocking knot-releasers. Fig. 4 is a perspective of one of the sliding arms. Fig. 5 is an enlarged horizontal section of one ofthe sliding arms and a knot-releaser. Fig. 6 is a side elevation, the parts in same relative positions as shown at Fig. l.

This invention relates to corn-planter checkrowers of that class which are actuated by a knotted wire or cord stretched across the field;

`and it consists, first, in the use of sliding arms pivoted to an oscillating bar and projecting in different directions, so that each knot on the wire or cord will act upon one of the sliding arms, to push it backward, and thereby retract the other sliding arm, so that the same knot may act upon it to draw or pull it rearward, and thereby restore the arrnfirst acted upon to its original and normal position, and in position to receive a similar impulse from the next succeeding knot, whereby both a forward and return stroke may be given to the planter seeding devices by each knot on the check-row wire or cord; second, in combination with the sliding arm upon which the knots of the check-row wire or cord act, a camblock which deilects the wire or cord and releases the knot from the sliding arm.

The invention further consists in constructions and combinations hereinafter described, and set forth in the claims hereto annexed.

Referring to the drawings by letters, letter A represents a bar to which the working parts 5o are connected, as hereinafter described.

B is a bar, pivoted tothe bar A at b.

C is a sliding arm, pivoted at one end to one end of the bar B, and its other end provided with a head or enlargement, 0,011 one side, which has a groove, c, as shown at Fig. 4. A lug, c", projects from the under side of the head c, through a straight slot, b', in the bar A, and causes the head c to reciprocate in a straight line when the bar B is oscillated.

C is a sliding arm, pivoted at one of its ends to the opposite end of the bar B from the bar O, and its other end projecting from the bar B in an opposite direction from the bar C, and provided with a grooved head, c, similar to the head o on the bar C, and a lug, c", which operates in a slot, b', in the bar A, same as the similarly-lettered parts on the end of the arm C.

DD are blocks. pivoted at d d', respectively,

one to each end ofthe bar A, and adjacent to 7o the paths of the heads c. The forward end of each block D Dl has a groove, d", in its face next to the head c, to prevent the knots on the check-row wire catching on the block, and the rear ends of the blocks D D have'each a groove, 7 5 d, in its same side as the groove d, through which the knots pass, as hereinafter described. Each block D D' has a lateral projection, c, from its side next the head c, and a cam, E, extends forward from each projection e, and is 8o pointed at its forward end, its cam-face side next the groove d being about parallel with said groove and at such distance therefrom as will permit the knots on the check-row wire to pass between the cam and the groove. 8 5

A link, F, connects the oscillating bar B with one end of an elbow-lever, G, the other end of which is connected, by a link, H, with the ordinary slide-bar, I, which connects the seed-slides of the planter. 9o

J is a check-rowwire or cord with ordinary knots, j, at distances apart equal to twice the distance between the hills of corn to be plan ted.

K is a staple or guard for the knotted wire or cord.

In operation the device may be placed centrally and with the bar A transversely to the planter, and only one of the bars A and its attached devices be used; but I prefer to place a bar, A, with its attached working devices, at each side of the planter, and so that each bar A mayl move forward with the planter in the direction shown by the arrow at Fig. l. At Fig. l a knot, j, is in position to commence to act on the head c of the arm C, and as the planter advances will force the arm C backward, and thereby oscillate the bar B and draw the arm C forward` to the positions shown at Fig. 2, and at the same time oscillate the elbow-lever G, and thereby operate the planter-seeding devices. In moving the head c of arm C rearward the cam E will pass between the knot j and block D, as shown at Fig. 5, and deflect the knot or force it to one side, so as to release it from the head c' and allow it to pass backward through the groove d" and between said groove and the cam E. As the planter continues its forward movement the same knot which acted on the head c ofthe arm G will next act upon the head c of the arm C in a similar manner, but on the end of the head next the arm, instead of its extreme outer end, and will draw the arm C rearward, and thereby force the arm C forward, ready for the action of the next knot, and at the same time again operate the seeding` devices. The knot is released from the head c on the arm C by the cam E on the block D in a similar manner to the release from the head on the arm C, already described.

The blocks D D may be rigidly Xed to the barA; but I prefer them pivoted, to facilitate their operation in receiving` and releasing the knots.

What I claim as new is- 1. In a corn-planter, the combination, with a knotted check row wire or cord, of sliding arms projecting in different directions, and pivoted to an oscillating bar, so that each knot on the wire or cord will act upon one of the sliding arms to push it backward, and thereby retract the other sliding arln, so that the same knot may act upon it to draw or pull it rearward, and thereby restore the arm rst acted upon to its original position, ready to receive a similar impulse from the next succeeding knot, substantially as and for the purpose specified. i

2. In combination with a knotted check-row wire or cord, sliding arms 0 C', projecting in different directions, and pivoted to an oscillating arm, B, so that each may act upon the other, and so that they may be each carried rearward and each carried forward by the action ot' each and every knot passed in contact therewith on the check-row wire or cord.

3. In combination with a knotted check-row wire or cord,and with sliding arms C C', having heads moving in a straight or nearly straight line, cams E, arranged to defiect the knots on the wire or cord, and thereby release them from the sliding arms.

4. In combination with a knotted check-row 5. In combination with a knotted check-row wire or cord, and with sliding arms C C', having heads c moving in a direct line or path, pivoted blocks D D', having cams E on their face next the arms C C', substantially as and for the purpose specied.

6. In combination with a knotted check-row wire or cord, and with sliding arms C C', having heads o, moving in a direct line or path, pivoted blocks D D', having cams E and grooves d", substantially as and for the purpose specied.

In testimony whereof I at'x my signature in presence of two witnesses.

LORENZO D. BENNER.
